Last summer my partner and I split up as I caught him texting a female colleague. It wasn’t work related and we split over it. We got back together int he autumn and he has since moved to another depot . He works closely with a new female colleague that’s started and it makes me feel uncomfortable. They text random stuff on the weekend to each other about what they’re doing and I find it inappropriate. He is saying I’m not allowing him to have friends and I feel like I’m just an insecure woman, but why do you need to be texting on the weekend? He works away a lot as part of his role and I feel Like considering what’s happened I give him a lot of trust . Thoughts ?
